This kind of “awww” reaction sound is widely used online as a general-purpose audio cue rather than being tied to one clearly documented source. It spread through meme edits, reaction compilations and short-form videos where creators needed a fast emotional response for cute, awkward or unlucky moments. Its staying power comes from how flexible it is: the same clip can read as sincere, teasing or ironic depending on the timing, the visual setup and the pacing of the edit.
